DRINKING WATER CASE STUDIES AND WHITE PAPERS

• Expansion And Upgrade Of WWTP Ozone Disinfection System Reduces Energy Cost By 69%

  The financial cost to maintain their ozone equipment, and increasing scarcity of replacement parts for their ozone generator, motivated a utility in Springfield, MO, to upgrade their ozone system. Read the full case study to learn how the plant assessed the energy cost of a sidestream ozone injection system compared to that of a turbine mixing design and showed that the Mazzei retrofit design reduced the energy cost of ozone contacting by an average of 69.2% under all plant flow conditions.

• Innovative Project In Virginia Changes Lens On Wastewater

  In September of 2016, Ted Henifin took the first sip of water purified at a pilot treatment plant developed by HRSD (Hampton Roads Sanitation District). Now, the innovative water treatment program known as SWIFT — Sustainable Water Initiative for Tomorrow — is changing the lens through which communities and government officials view wastewater, drinking water, aquifer replenishment, and even fighting sea level rise.

• Treating Trace Contaminants In Drinking Water - Aurora, Colorado

  To protect residents from environmental contaminants, the City of Aurora set stringent water treatment goals, and adopted an advanced treatment process at the Aurora Reservoir Water Purification Facility.

• What's Missing From Your Water-Monitoring Strategy?

  When it comes to water quality monitoring, professionals in municipal, industrial, and agricultural applications might have distinctly different concerns about what they measure, but they all share a common concern about the cost and ease of obtaining that data. Fortunately, a new alternative for achieving water quality data and analytics with a high degree of autonomy, accuracy, and affordability is now available to all of them.

• Long Term Performance Of V-Cone Flow Meters

  This paper presents the results of 12 V-Cone DP Flow meters tested over a period of 17 years. Service applications for the V-Cones included natural gas as well as coke oven gas measurement, a dirty aggressive fluid that is problematic over long period of time for most flow meters. All testing was conducted in air by a 3rd party calibration laboratory, CEESI Colorado. Results will be presented for each of the meters over the 17 year span. Conclusions and recommendations will be made to the long term performance and recalibration intervals for the V-Cone flow meter.

• Tri-City Water Infrastructure Partnership: When 'We' Is Better Than 'Me'

  This is a story about three cities in North Carolina: Albemarle, Concord and Kannapolis. Albemarle, 40 miles east of Charlotte, had excess capacity in its water system and needed new customers to defray costs.

• NE Alabama Water District Case Study Northeast Alabama Water District (NEAW) services 15,200 connections within 2,052 square miles, resulting in a very large distribution area.
• Supercharging Acoustic Leak Detection With Analytics

  The integration of advanced analytics can take acoustic leak detection systems to another level by leveraging noise filtering, pattern recognition, and comprehensive data analysis.

• Use Of UV Technology Gaining Acceptance Within Process Industries

  The use of Ultra Violet (UV) technology within process industries has grown tremendously in recent years. Water, fruit juice, syrup and brines are increasingly seen as the largest volume ingredient in many food products, and the need to protect human health, whilst reduce the level of chemical preservatives, and to extend shelf life leads to the incorporation of UV systems within the food manufacturing process.

• Condition Assessment At Spring Creek Ranch

  Learn why Spring Creek Ranch chose Echologics to survey 1.7 miles of 12-inch ductile iron pipe, utilizing the ePulse® method to assess the condition of the over 40-year-old pipes.
